How can this problem be solved?


------ Solution --------------------
Basename ();
Look at the manual
------ Solution --------------------
$ Str = "index. php ";
$ Str = strsub ($ str, 0,-4); // get the last and fourth digits from the first place, that is, get something before. php!
Echo $ str;
Or use a string to separate! But I think that's troublesome!
------ Solution --------------------
$ _ SERVER ['script _ filename']
------ Solution --------------------
Basename ($ _ SELF, '. php ')
------ Solution --------------------
Same as above
